Accuracy of Patient Positioning in Mantle Field Irradiation
Medical Dosimetry, 1992A prospective study of the accuracy of patient positioning in mantle field irradiation was carried out in 13 lymphoma patients treated with curative radiotherapy. Patients were treated in the supine and prone position for anterior and posterior fields, respectively.

Accuracy of position and track
2004Catastrophic marine accidents are rare. Of those collisions and standings which do occur, many start as quite routine navigational situations; just another night, just another watch, just another target. Something then goes awry perhaps the radar fails to display an islet or a target's calculated closest point of approach (CPA) is erroneous ...

UWB positioning accuracy and enhancements
TENCON 2017 - 2017 IEEE Region 10 Conference, 2017Requirements of different applications and usage scenarios on a wireless positioning system is very different. A single positioning system is unlikely to meet all the requirements. UWB based positioning systems offer a solution which would meet all the indoor usage requirements.

Positioning Accuracy Improvement With Differential Correlation
IEEE Journal of Selected Topics in Signal Processing, 2009The success of satellite navigation in the mass consumer market will depend greatly on its performance in deep urban and moderate indoor environments. The signal obstructions in these environments lead to low signal-to-noise ratios, which substantially degrade the positioning accuracy of GPS and Galileo receivers. New ranging techniques are required to

LTE Positioning Accuracy Performance Evaluation
2015In this paper we investigate the positioning accuracy of user equipment (UE) with observed time difference of arrival (OTDoA) technique in Long Term Evolution (LTE) networks using dedicated positioning reference signal (PRS) by means of comprehensive simulation model.

Position Accuracy of Drilled Holes
CIRP Annals, 1991When selecting hole-making sequences, the positional accuracy mainly is determined during the first drilling operation. This dissertation consists of three papers which consider the influence of various factors on hole positional accuracy when drilling in inclined workpieces using high-speed steel twist drills with conventional point geometry.

The Accuracy of Microtargeted Policy Positions
Political Science and Politics, 2016ABSTRACTIdentifying voters who share policy positions with the candidates has become an important component of modern political campaigns as they rely on microtargeted estimates to guide targeting decisions. Using survey data and microtargeted estimates from the 2012 election, I conduct one of the first independent examinations of the accuracy of ...

On the accuracy of satellite position determination
Planetary and Space Science, 1964Abstract A computer programme is described by means of which the errors in computing the position of a satellite in orbit can be estimated from the covariance matrix of errors in the orbital parameters. The programme is used to show that orbital parameters of Ariel 1 derived from Minitrack data are good enough for the position of Ariel to be ...
